Open the App Store (Applications folder or on the Dock.) Sign in with your Apple ID and password. Find the Mountain Lion download. Click on the purchase button (the one that displays the purchase price.) When the purchase is recorded the button will change to Download (or Install.) Click on the button and wait for the download to finish. It's 4 GBs so it can take up to a few hours depending on the speed of your Internet service.
When the download is complete the installer will launch automatically. Before you proceed I suggest reading:
Make Your Own Mountain/Lion Installer
1. After downloading Mountain/Lion you must first save the Install Mac OS X Mountain/Lion application. After Mountain/Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Mountain/Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
3. Locate the saved Mountain/Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
4. Plug in your freshly prepared USB flash drive. You are going to clone the content of the InstallESD.dmg disc image to the flash drive as follows:
When the clone is completed you have a fully bootable installer that you can use without having to re-download Mountain/Lion.
Note: The term Mountain/Lion used above means Lion or Mountain Lion.
As an alternative to the above you can try using Lion DiskMaker 2.0 that automates the process.
Thanks so much for that Kappy. Ready to proceed.

Here's yet another question about upgrading from OSX v 10.6.8 (Snow Leopard) to OSX Mountain Lion. We have 2 PC's (both with iTunes & iCloud & iTunes Match. I have all my music on my office PC but with iTunes Match the music is in "The Cloud" and available to our 2 iPad's (iPad 3 & iPad 4). Our iMac (late 2006 model) is not connected to "The Cloud" because it's OSX is Snow Leopard 10.6.8. I would LOVE to upgrade to Mountain Lion and be able to access "The Cloud" and all my music BUT in the Tech Specs for Mountain Lion it states that one of the requirements is: an iMac that is a 2007 model or newer. Our iMac is a late 2006 model 2.16 GHZ Intel Core 2 Duo with 3 GB of 667 MHZ DDR2 SRAM. What changes were made between the late 2006 iMac and the 2007 iMac that would make the 2006 "NOT UPGRADEABLE" 😕 😕
You need 4GB of RAM
Would it work just as well to copy the downloaded installer of Mountain Lion on to a DVD?
